GEn1E-1124-002 is a two-part Phase 2 study to evaluate the safety and tolerability of GEn-1124 in subjects with ARDS. Treatment with IV infusion dosing as early as possible after ARDS diagnosis. Subjects will be given a second dose approximately 8 hours after the first dose and will continue with twice daily dosing (BID regimen) for 5 days.
Randomized , double-blind, placebo controlled, dose escalation study to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), safety, and tolerability of GEn1124.
GEn-1124 or placebo will be administered as a 2-hour IV infusion as early as possible after ARDS diagnosis. Participants will receive a second dose approximately 8 hours after the first and will continue BID for the remaining schedule (Days 2-5). Follow-up will be for a total of 60 days after the first dose or death (whichever comes first).
An independent Safety Review Committee (SRC) will be responsible for reviewing data throughout the study.

All subjects, investigators, and study personnel involved in the conduct of the study, including data management, will be blinded to treatment assignment with the exception of some designated personnel. The unblinded study personnel will not participate in study procedures or data analysis prior to unblinding of the study data to all study-related personnel.

| Change in ratio of arterial oxygen partial pressure to fractional inspired oxygen. |
Ratio of arterial oxygen partial pressure to fractional inspired oxygen is calculated as PaO2 / FiO2 where PaO2 indicates arterial oxygen partial pressure and FiO2 indicates fraction of inspired oxygen. All values are derived from ventilator parameters and arterial blood gas. |
| Through study completion, Day 60 |
| Change in static compliance. | Static compliance is calculated as the tidal volume divided by the difference between airway plateau pressure and end-expiratory pressure (Pplat - PEEP) where Plat is airway plateau pressure and PEEP is positive end-expiratory pressure. All values are derived from ventilator parameters. | Through study completion, Day 60 |
| Change in dynamic compliance. | Dynamic compliance is calculated as the tidal volume divided by the difference between peak inspiratory pressure and end-expiratory pressure (PIP - PEEP) where Plat is airway plateau pressure and PEEP is positive end-expiratory pressure. All values are derived from ventilator parameters. | Through study completion, Day 60 |
| Change in the Radiographic Assessment of Lung Edema (RALE) score | To calculate RALE, each radiographic quadrant is scored for extent of consolidation (0-4) and density of opacification (1-3). The product of the consolidation and density scores for each of the four quadrants is summed (minimum score=0, maximum score=48; higher scores mean worse outcome). | Through study completion, Day 60 |
| Duration on invasive mechanical ventilation. | Duration of invasive mechanical ventilation is defined as the number of hours that the subject receives invasive mechanical ventilation for at least 1 hour duration. | Through study completion, Day 60 |
| Duration of any ventilatory support. | Duration of ventilatory support is defined as the number of hours that the subject receives any ventilation support for at least 1 hour duration. | Through study completion, Day 60 |
| Number of Ventilator Free Days (VFDs) | VFDs to day 28 are defined as the number of days from the time of initiating unassisted breathing to day 28 after randomization, assuming survival for at least 48 hours after initiating unassisted breathing and continued unassisted breathing to day 28. If a subject returns to assisted breathing and subsequently achieves unassisted breathing to day 28, VFDs will be counted from the end of the last period of assisted breathing to day 28. A period of assisted breathing lasting less than 24 hours and for the purpose of a surgical procedure will not count against the VFD calculation. If a subject was receiving assisted breathing at day 27 or dies prior to day 28, VFDs will be zero. Subjects transferred to another hospital or other health care facility will be followed to day 28 to assess this endpoint. | Up to Day 28 |
| Intubation (in subjects not previously intubated) | Intubation is defined as the need for initial intubation in subjects who are not intubated at baseline. | Through study completion, Day 60 |
| Reintubation (after extubation) (if applicable). | Reintubation is defined as the need for reintubation after initial successful extubation for 48 hours. | Through study completion, Day 60 |
| Change in Sequential Organ Failure Assessment (SOFA) score. | The SOFA score is used for prediction of mortality in ICU patients. Initial and highest scores of more than 11 or mean scores of more than 5 corresponded to mortality of more than 80%. | Through study completion, Day 60 |
| Incidence of hospital mortality. | Hospital mortality is defined as mortality that occurred during hospitalization up to Day 28, defined as 672 hours from the time of randomization. All subjects will be classified as either "alive at Study Day 28" or, if dead, "dead at Study Day 28." | Up to Day 28 |
| Incidence of all-cause mortality. | All-cause mortality is defined that occurred for any cause up to Day 28, defined as 672 hours from the time of randomization. All subjects will be classified as either "alive at Study Day 28" or, if dead, "dead at Study Day 28." | Up to Day 28 |

| Duration in hospital. | Length of hospital stay will be defined as the number of hours hospitalized for at least 1 hour duration. | Through study completion, Day 60 |
| Proportion of subjects alive and free of respiratory failure or extracorporeal membrane oxygenation (ECMO)). | Alive and free of respiratory failure is defined as being alive without the need for invasive mechanical ventilation, non-invasive ventilation, high-flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates >20 L/min with fraction of delivered oxygen ≥ 0.5), or extracorporeal membrane oxygenation (ECMO). | Through study completion, Day 60 |
| Hierarchical Alive and Ventilator Free (AVF) score. | To compute AVF, each subject is compared to every other subject in both trial arms and assigned a score (win=+1; lose=-1; tie=0) for each pairwise comparison, based on which fared better. | Through study completion, Day 60 |
| Time to recover gas exchange | Length of time is defined as the number of hour to recover gas exchange to PaO2/FiO2 ³ 300 for at least 24 hours. | Up to Day 28 |
